STEAM FEED-WATERTRAP.

SPECIFICATION forming part of Letters Patent No. 358,964. dated March 8,1887.

Application filed July 9, i886. Serial No. 207,542. (No model.)

To all whom it may concern:

Be it known that I, HENRY CREAMER, of the city, county, and State of NewYork, have invented certain new and useful Improvements. in SteamFeed-Vater Traps, of which the folwater into the boiler when a certainquantity of such feed-water has collected.

The object of my invention is to provide an automatic feedwater trap inwhich the eX- haust-steam of the trapis carried from above the upperpiston to a point below the same, and is then forced into t-he pipethroughwhich the water of condensation is conducted to the trap.

The invention consists in the' construction and combinations of partsanddetails, as will be fully described and` set forth hereinafter, andfinally pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal sectionalelevation of my improved feed-trap. Fig. 2 is an enlarged'detail view ofthe valve movement. Fig. Sis a plan View of the same, parts beingomitted. Fig. 4. is a longitudinal sectional elevation of theslide-valve, and Fig. 5 is a diagram view showing the generalarrangement of the trap.

Similar letters of reference indicate corresponding parts.

' The steam-cylinder A and the smaller water- `cylinder B are cast inone piece, the latter cylinder being provided a short distance bel'oWits upper end with an internal annular shoulder, B', on which apacking-ring, C, is placed and held in place by an angle-iron ring, C',through which bolts C2 are passed into the annular offset or shoulder D,forming the bottom of the steam-cylinder A. The said cylinder A isprovided with suitablehand-holes, a, which can be closed by suitablecovers held in place by suitable means.

The piston E in the water-cylinder B and the piston G in thesteanrcylinder A are connected by the rod F. i

The water-cylinder is provided in its bottom With the opening I, whichis in communication with the pipe J, having the checkvalves J and J2 atopposite sides of the aperture I, the said check-valves both opening inthe same direction,the water passing through the pipe J in the directionof the arrow d. A pistonrod,H,passes to the stuffingbox H on the top ofthe steam-cylinder A, and is provided at its upper end with ahead, H2,through which head is fastened one end of a chain or metal strap, K,passed over the roller L,piv

oted on one end of the lever L, pivoted on a standard,L`l,on the top ofthe cylinder A, the other end of the metal strap or chain K beingfastened to said standard. A weight,L3,isfast ened or held on the otherend of the lever L to counterbalance the two pistons.

A headed pin, M, projects from the head H2 on the top of the piston-rodH, and passes through a longitudinal slot, M', of a vertical rod or bar,M2, the lower end of which is pivoted to the arm O of a sleeve,O,'nnounted loosely on the pivot O2, projecting from the side of ahorizontal cylindrical valve-casing, P, on the head of the cylinder A.Said sleeve O is provided with a collar, O3, havinga recess, Ot, thelength of which is about equal to one-third of a circle. Into the saidnotch or recess O4 a pin, Q, passesfrom a lever, Q,

stem R2 ofthe sliding valve P in the casing P. `The neck P2 of thecasing P is connected with the cylinder A. vThe neck P3 of the casing Pis connected with the boiler m by the pipe o, and the casing P isconnected by apipe, S, with the bottom part of the cylinder A. The pipeJ is connected by a pipe, n, with the boiler m. The lower part of thepipe J is connected by the pipe 1', having the check-valve s, with thepipe p.

A pipe, V, forms connection between the pipe p and the pipe J, andwithin a frame,- t, fastened on the side of the cylinder A, anenlargement, t', is formed in the pipe V, on the side of whichenlargement the boX t2 is formed.

IOO

A rock-shaft, t3, is mounted in the box t2, and is provided with an arm,projecting into the enlargement t', from which arm i* a float, t5, issuspended or supported in any suitable manner. The shaft t3 is providedat one end with an arm, s', carrying a ball, s2. The arm s is connectedby a rod, Il, with an angle-lever, t', pivoted on top of the frame t,the other end of said angle-lever being connected with the sliding boltj, the end of which can pass 4into the notch 7c in the collar o",mounted on the pivot O2.

The operation is as follows: The water of condensation passes throughthe pipe J in the direction ot' the arrow d, Fig. l, opens the left-handcheck-valve J passes into the watercylinder B, and exerts an upwardpressure on the bottom piston, C, which, with the upper piston, E,rises. The lever L swings down and the metal strap or chain K draws thepistonrod and valve upward. As the upper piston, E, ascends theexhaust-steam above the same passes into the valve-casing P, the valvebeing'in proper position, and then down through the pipe S into thebottom part of the steamcylinder below the steam-piston. The valve isthen reversed, so as to admit live steam into the upper part of thecylinder A, which steam, acting on the large upper piston, forces thesame downward, whereby the lower piston, C, of the water-cylinder forcesthe water out through the aperture I into the pipe J and check-valve Jinto, the boiler. At the same time the piston E forces theexhaust-steam, which was conducted from above the upper piston to belowthe same, through the pipe fr into the pipe p, through which the returnor condensed water of condensation passes from the engine-register, Src.The exhaust-steam of the steam-trap is thus mixed with the return orwater of condensation coming from the register or engine. Vhen -thepistons E and G are forced downward, the piston-rod II is also moveddown, and the metal strap or chain acting on the lever L swings theweighted end of said lever upward, and so on. When the pistons havecompleted their upward stroke, the headed pin M on the upper end of thepiston-rod H strikes against the upper end of the slot in they verticalrod or bar M2, and swings the same upward, thereby swinging the arm O inthe direction of the arrow a', Fig. l. Then one end of the recess ornotch O4 strikes the pin Q, thereby throwing the arm Q out of a positionof rest in the direction of the arrow a2. Under the action of the weightQ the rocking arm continues the stroke in the direction of the arrow c2,and the left-hand shank, Q*,striking the lug R of the U-shaped rod R,moves said rod, and the piston valve j in connection with the same, inthe inverse direction of the arrow a2, whereby the valve is shifted insuch a manner as to admit live steam into the upper end of the cylinderA, under the action of which live steam the pistons are moved downward.Vhen the pistons have completed their downward stroke,

the headed pin M strikes the arm O and presses the same in the inversedirection of the arrow c',- whereby the other end of the recess O4 inthe collar O3 strikes the pin Q and swings the lever Q in the inversedirection of the arrow a2 until said lever has passed its center, whenit continues to swing in the inverse direction of the arrow a2 under theaction of the weight Q. Thereby the valve is shifted in the direction ofthe arrow c?, the live steam cutoff, and the communication establishedbetween the cylinder A and pipe S.

It is not desirablethat the apparatus should operate when there is notsufficient water in the pipes, and for this reason I have provided theenlargement t andk the iioat in the same. The level of the water in thepipe Vis always equal to the level of thewater in the cylinders. Vhenthe level of the water in the cylinders and in the pipe p is high, theiioat t5 is raised and the weight sl lowered, and the bolt j iswithdrawn from the notch 7c in the collar 0, and thus does not interferewith the operation of the valve mechanism. Vhen the level of the watersinks, the iioat i5 descends, the rod h is moved upward, and the end ofthe bolt or latch j is pushed into the notch 7c, whereby the valvemechanism is locked. rlhe valve mechanism is thus always locked when thelevel of the water in the apparatus is too low, and is released when.the level of the water rises to the proper height.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl.
